Hi All

Have a very quick question, is 10GBe backwards compatible to gigabit equipment when using a copper link?

I am doing some future planning and would like to start rolling out 10GB equipment for our backbone next year.

Cheers

Yes. It will negotiate down to gigabit speeds.

The new IEEE 802.3bz standards for 2.5GBASE-T and 5GBASE-T due later this year should help extend the life of installed Cat5e/Cat6 cable too, by pushing them to 2.5Gbps and 5 Gbps up to 100m.

im very much keen to see particularly 2.5Gbit come to life, an asset to small gbit based lans where we see 1gbit peaking, but 2.5Gbit would be hitting non ssd IO limitations. 5gbit would be awesome for between switches.

Heres hoping it comes at the pricepoint we all are expecting it will.

Personally im currently looking at 10Gbit links between a few key points in my home network.

Recently Online.net have taken up a massive outlay on their network over Base2500X, that a major party to already take up BASE2500 be it on the X rather than T variant.

Yes. You may have to check that any 100baseTX gear is compatibile with it though, but I expect you would have already picked up any problems when plugging it into a Gigabit switch. Keep in mind that 10GBE has higher latency that 1000baseT, so if thats an issue then multi-mode fibre is another popular choice.

If you plan to use direct-plugged SFP+ type cables, then keep in mind that they are sometimes keyed to only work with certain manufacturer's equipment and you need to check for that.

Qualified in business, certified in fibre, stuck in copper, have to keep going ^_^
